Abstract: AlM: To evaluate the clinical efficacy of canalicular intubation combined with external dacryocystorhinostomy ( ext-DCR ) for treatment of chronic dacryocystitis and upper lacrimal duct stenosis.
METHODS:Thirty-three patients (33 eyes) with chronic dacryocystitis and upper lacrimal duct stenosis who underwent canalicular intubation combined ext-DCR were retrospective analyzed. The silicon tube was indwelt for 6mo. All cases were re-examined 1wk;1, 3, 6, 9mo post-operation, flow of tears, pus excretion and lacrimal duct clearance were observed.
RESULTS: Clear lacrimal duct ratio was 100% in all cases during 1wk~6mo post-operation; Silicon tube was removed 6mo post-operation, 3mo after tube removal, rechecking reported 32 cases with clear lacrimal duct (97%) and 1 case with resistant duct (3%). Two cases ( 6%) with minor lacerations, no other complications were observed.
CONCLUSlON: Canalicular intubation combined ext-DCR is an effective treatment for chronic dacryocystitis and upper lacrimal duct stenosis.
